Title: Solvent de-asphalting of heavy petroleum residues - at elevated temps in presence of water, giving improved sepn and easier processing
Inventor: MALIKOW FATKULLA CHAJRULLOWITS
IPC: C10G21/00
Filed: 1972-12-12
Abstract: Atmospheric or vacuum distn. residues are treated with 4-8C paraffins in presence of >=2% water (based on vol. of oil) at >=100 degrees C, and below the criticl b.pt. of the solvent, the water passing into the raffinate phase. Extn. is pref. at 140-190 degrees C, wit a ratio of solvent to oil of 2-5:1. The water, with density between that of the extract and the asphaltene concentrate, displaces the solvent from the latter and increases the efficiency of the extn. process. Water-soluble salts are removed from the extract, and the viscosity of the asphaltene concentrate is reduced, together with its tendency to stick to the walls of the extn. equipment.

Title: Anti-aquaplaning system for vehicles wheels - has aerodynamic blades diagonal beneath vehicle to provide water deflecting flow
Inventor: TODTENHOEFER MANFRED
IPC: B60B39/00
Filed: 1974-02-01
Abstract: The system consists of two aerodynamic blades, which are movably mounted, and positioned at an angle of 90 deg., in front of the vehicle wheels. During travelling, the oncoming air is concentrated by the blades, and pressed onto the road surface, thereby removing the surface water from the road in front of the wheels. Smal castor wheels on the tips of the blades deflect them upward on uneven surfaces to prevent contact with the road surface. The angle of the struts is controlled by fluidic struts, to allow lifting clear in dry conditions.

Title: Oil and fuel lubrication for combustion engines - oil-fuel mixture is matched to engine operating condition
Inventor: REINHARDT GERD
IPC: F02B75/02
Filed: 1974-03-11
Abstract: Fuel drawn from a tank by a fuel pump is mixed with oil supplied from an oil pump of an engine in a valve before being supplied to a carburettor feeding the engine. The oil/fuel ratio is varied by a monostable multibrator in response to variations in carburettor throttle spindle position engine speed as sensed at the distributor, and oil pressure, and oil temperature as sensed by the sensors respectively. The two oil temperature sensors are used to distinguish when a steady operating temperature is reached. The inputs from the throttle spindle and the sensors are passed to the multivibrator via a summing circuit. System has advantages that sufficient engine parameters are observed to accurately control oil/fuel ratio.

Title: Appts. for coating articles with sugar - consisting of cylindrical perforated container closed by stationary end pieces
Inventor: HUETTLIN HERBERT
IPC: A23G3/26
Filed: 1974-09-20
Abstract: Appt. for coating articles with sugar consists of a cylindrical container which is rotatable about >=1 approx. horizontal axis and has in it walls perforated regions for introduction/removal of a drying gas, esp. warm air. Both ends of the cylinder are closed by sections which remain stationary during operation and have perforations at least in those areas adjoining the lower part of the container and are fastened to air feed/outlet lines. Sections are removable or pref. hinged to permit opening of the container. Cylindrical shape ensures forced aeration and since perforated areas are stationary, a fixed relative velocity between the articles being coated and the perforations is achieved; this prevents blocking of the holes by incompletely dried matl. The appt. takes up little space and is safe since all moving parts are enclosed.

Title: Multiple carrier frequency generating system - for pre-modulators generates twelve carriers at four KHZ intervals from basic four KHZ
Inventor: SCHWERTZEL HEINRICH DIPL ING
IPC: H04J1/06
Filed: 1974-10-02
Abstract: The multiple carrier frequency generating system, for pre-modulators, generates channel carriers of 112 to 156kHz at spacings of 4 kHz, and the premodulation frequency of 48 kHz all form a 4kHz fundamental by converting to pulses, filtering, multiplying and amplifying. The 12 and 28 kHz harmonics are produced and are converted into rectangular-wave pulses to give - along with the converted 4 kHz - three basic signals that can be multiplied by various integers to give the required total of 13 output signals. The advantage of the generating system is that the number of filters required is reduced.

Title: Overload protection circuit for loudspeakers - has temperature sensor monitoring vibrating coil and controlling output power of amplifier system
Inventor: BACKES WOLFGANG
IPC: H04R3/00
Filed: 1974-10-11
Abstract: The overload protection circuit, for loudspeakers, has a temperature sensor which is used to reduce the output power of the amplifier according to the temperature of the vibrating coil. The temperature sensor may be a temperature sensitive resistor which is kept in good thermal contact with the vibrating coil, or it may be the coil itself -- i.e. changes in the resistance of the coil due to changes of temperature may be monitored. Another method uses an electronic model of the behavious of the loudspeaker and obtains the criterion for controlling the input power from this.
